Purpose: Women's weight perception and obesity-related quality of life were analyzed according to BMI (Body Mass Index). Methods: A survey was conducted using self-report questionnaires from 178 participants. The data analysis included descriptive statistics, frequency, percentage, t-test, ANOVA, Fisher's exact test and Kendall's tau using the SPSS version 14.0. Results: There were significant differences in BMI according to age (F=8.037, p=<.001), weight perception (F=60.71, p<.001), weight control experience (F=2.504, p=.013), weight control method (F=5.839, p=.001) and weight control success (F=-2.451, p=.016). There was a significant difference in obesity-related quality of life according to weight perception in the low weight group (F=5.587, p=.021) and in the obesity group (t=3.419, p=.003). Higher correlations were found between the women's BMI group, weight perception and obesity-related quality of life. Conclusion: A program to provide appropriate information for weight perception is needed for the low weight group. There is a need for a program about weight reduction as well as weight perception for the obesity group.

Objectives: This study was to investigate how body-shape perception could influence to weight control practice both in normal and obese group. Methods: We used 2012 Korea National Health and Nutrition Examination Survey to analysis 1) weight control practices of population; 2) consistency between body-shape perception and body mass index; 3) comparison weight control practices between normal group and body mass index (BMI) obese group in perceptional obese group; 4) odds ratio of BMI obese group using herbal drugs for weight control practice in perceptional obese group. Results: We found that study population tends to choose exercise, dietary restriction, meal skip, health functional food, one-food, drug, herbal drug, fasting and self-medication in order of frequency to control weight. The agreement between body-shape perception and BMI within obese group was approximately 64% with 0.40 of Cohen's Kappa coefficient, ranging from 0.384 to 0.423. Within perceptional obese group, choosing each weight control practice methods ratios between normal BMI group and obese BMI group were not significantly different. Within perceptional obese group, obese BMI group showed significant odds ratio (2.58, 95% confidence intervals, 1.38~4.85) than normal BMI group in choosing herbal medication for weight loss when adjusting other variables. Conclusions: We concluded that body-shape perception might be an important factor for choosing weight control program, and roles of Korean medical doctors thought to be enhanced for using herbal medication for weight loss.

Objectives: The purpose of this study was to investigate the effect of the perception on the quality of nosocomial infection control on perceived risk, trust, and the intention to revisit among the medical consumers. Method: 361 patients and their guardians who were hospitalized in women's hospital, Gangnam-gu, Seoul, participated in this study. The data was analyzed using SPSS Statistics 21.0. Results: The perception on the quality of nosocomial infection control had a negative(-) effect on perceived risk, a positive(+) effect on trust, a positive(+) effect on the intention to revisit. The perceived risk had a negative(-) effect on trust, a negative(-) effect on the intention to revisit. The trust had a positive(+) effect on the intention to revisit. The perceived risk was partially mediated by the perception on the quality of nosocomial infection control and the intention to revisit, while the trust was fully mediated by the perception on the quality of nosocomial infection control and the intention to revisit. Thus, it indicated that the perceived risk and trust had dual mediated effects as well as full mediated effects in the relationship between the perception on the quality of nosocomial infection control and the intention to revisit. Conclusions: The nosocomial infection control can be an important factor to contribute to hospital management by attract the loyal medical customers, not just cost-expenditure. The nosocomial infection control can help hospital revenue and customer management strategy. Thus, it will contribute to the effective marketing strategy in the medical field.

The purpose of this study was to investigate the factors influencing health perception in the elderly, to provide the basic data for health behavior program and nursing intervention. The subjects of this study were 240 elderly person over the age 60, living in Seoul and Kangnung. They were conveniently sampled for this study and the data was collected from June 1999 to September 1999. The instruments for this study were the Health Perception Questionaire developed by Ware(1979), the OARS Functional Assessment Questionaire (Duke University 1978), and Multidimensional Health Locus of Control by Wallston, Wallston, and De Vills(1978). The data were analyzed by using SPSS Win computer Program. The results are as follows; 1. The total mean score of the health perception was 52.02(S.D=${\pm}$7.07) in a range of 33 to 69, and the mean score of the functional status was 27.02 (SD=${\pm}$2.75) in a range of zero to 28 and the mean score of the health locus of control was 65.66(S.D=${\pm}$8.68) in a range of 43 to 90. And The mean scores on the HLOC subscales were HLOC-I: 23.73${\pm}$4.56 (range: 6-30), HLOC-P: 23.07${\pm}$4.74 (range: 6-30), HLOC-C: 18.55${\pm}$4.03 (range: 11-30). 2. There was a significant positive correlation between health perception and functional status(r=.216, p=.001), and health perception and the health locus of control(HLOC) were not correlated at the level of statistical significance. However, the HLOC-I and health perception were correlated positively(r=.328, p=.000), and the HLOC-P were correlated negatively (r=-.129, p=.046). 3. There was a significant difference statistically in the degree of health perception according to the age(F=3.351, p=.002), spouse(t=2.232, p=.021), education level(F=7.373, p=.001), disease(t=3.639, p=.000), group activity (t=2.458, p=.015). drink(t=2.327, p=.021). 4. Stepwise multiple regression analysis revealed that the most powerful predictor of health perception was internal health locus of control. A combination of HOLC-I, functional status, HLOC-P, group activity explained 17.9% of the variance for health perception in the elderly. In conclusion, the results of this study show that internal health locus of control factor is very important in explaining the health perception for the elderly. Therefore, it will be considered internal health locus of control factor in nursing intervention and program in order to enforce the health behavior for elderly people .

Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

Objectives: Self perceived body image among women is drawing a lot of attention in Korea due to their unhealthy weight control behaviors. To determine the relationship between self-perceived body image and dietary behaviors among Korean women, the discrepancy between actual body size and body image perception, weight control behaviors were assessed based on age groups using the 2010 KNHANES data. Methods: A total of 1,747 subjects were selected after eliminating those of likely changing their diet recently using the 2010 KNHANES data. The subjects were divided into 3 groups, self-underweight, self-normal, and self-obese according to their perception of body image. The BMI and weight control behaviors were assessed based on age groups according to the body image perception. Results: The younger, the higher ratio of underweight, women perceived their body size as normal or overweight. Exercise and reduced food intakes were dominant among various weight control methods but unhealthy methods were dominant among self perceived overweight group. Conclusions: Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. Nutritional education should emphasize the importance of healthy weight and proper body image perception for Korean women.

The objective of this research is to monitor and control the vehicle motion in order to remove out the existing safety risk based upon the human-machine cooperative vehicle control. A predictive control method is proposed to control the steering wheel of the vehicle to keep the lane. Desired angle of the steering wheel to control the vehicle motion could be calculated based upon vehicle dynamics, current and estimated pose of the vehicle every sample steps. The vehicle pose and the road curvature were calculated by geometrically fusing sensor data from camera image, tachometer and steering wheel encoder though the Perception Net, where not only the state variables, but also the corresponding uncertainties were propagated in forward and backward direction in such a way to satisfy the given constraint condition, maintain consistency, reduce the uncertainties, and guarantee robustness. A series of experiments was conducted to evaluate the control performance, in which a car Like robot was utilized to quit unwanted safety problem. As the results, the robot was keeping very well a given lane with arbitrary shape at moderate speed.

The purpose of this study was to investigate the relationship between internal locus of control in children and parents' child rearing attitudes which children perceive. For this purpose, 198 fifth grade boys and 163 fifth grade girls were randomly selected and their perception of their parents' child rearing attitudes and their locus of control were measured. Children's locus of control was measured by A Locus of Control Scale For Children of Nowicki & Strickland (1973) which was translated into Korean and item analysis of which was done. Ami Children's perception of their Darents' child rearing attitudes measured by Parent-Child Relationship Inventory which was constructed in Korean Testing Center. For the data analysis, t-test and two-way analysis of variance were applied and Pearson correlation coefficient was computed. The results of the present study were as follows; 1. The correlations between children's perception of their parents' child rearing attitudes and locus of control in children were significant partly. Especially, internal children reported their parents as showing less rejective attitude and less different child rearing attitude between father and mother. 2, Sons were more influenced by their parents' child Learing attitudes than daughters in the development of locus of control 3. Maternal child rearing attitude was more influential than paternal child rearing attitude in the development of locus of control.
